Colleges should be held at least as accountable as tire companies are. When some Firestone tires were believed to be defective, government investigations, combined with news-media scrutiny, led to higher tire-safety standards. Yet year after year, colleges and universities turn out millions of defective products: students who drop out or graduate with far too little benefit for the time and money spent. Not only do colleges escape punishment, but they are rewarded with taxpayer-financed student grants and loans, which allow them to raise their tuitions even more.
